To all whom it 'ma/y concern:

Be it known that I, FRANK C. Gora, a citizen of the United States, residing atI the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Heating Systems; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art lo to Which it appertains to make and use the same, reference being had to the accompany ing drawings, and to the figures of reference marked thereon, which form a part of this specification. 'My invention relatos generally to improvements in heating systems but more specifically to means operated by the pressures Within the system for automatically controlling the supply of the heating agent. 2O The said means may be connected with the furnace which supplies thesteam, hot water or other agent, whereby' the dampers are automatically .adjusted both for the purpose of increasing` as well as for the purpose of" diminishing the draft of the furnace. In other Words the said controlling means may be so connected as to automatically open and close the dampers Whenever these operations are necessary. ln my improved construction as illustrated in the drawing, a motor device is employed, the same beinor provided `with a diaphragm which after r:the air is driven out of the radiators of' the heating system, and the pressure increases above atmospheric pressure owing to the fact that the air valves are closed, this pressure acts upon the diaphragm of the motor device which is connected With the'dampers of the furnace, whereby the front damper is closed and the rear damper or the air check opened. Again when the system becomes cooled and the condensation Within the radiators is sutlicient to produce a. partial vacuum, the vacuum pull acts upon the diaphragm of the motor device to more the same in the opposite direction, whereby thefront dann per is opened and the rear damper or air check closed.

Having briefly outlined my improved construction, I will proceed to describe the -same in detail reference being made to the accompanying drawing in which is illustra-ted an embodiment thereof.

ln this drawing, Figure l is a side elevation of a furnace and boiler shown in convdownwardly from this pipe nection with the heating system, my irnproved devices being connected therewith in operative relation. Fig. 2 is ajfragmentary View of the operating' devices, shown in a different posit-ion from that disclosed in Fig. l and on a larger scale. Fig. 3 is a similar View of the same showing the operat-- ing devices in still a different position. Fg. 4 is still another View illustrating operati ing devices shown in connection with the? motor device. ln this view the parts shown in the position 'when there is a vacuum Within the heating system, the dia phragm of the motor device being `actuated to open the dampers of the furnace. To

The same reference characters indicate the same parts lin all Vlthe views.

Let the numeral 5 designate the furnace and boiler for slxpplying the heating agent to a system. lt may be assumed that heating agent Whether steam or het Water passes from the furnace through af pipe 6 which may be termed. the supply pipe. A branch pipe 7 leads from the 'pipe 6 to each radiator 8, the latter being provided with Van automatic air valve 9. l-"ls shown in the drawing a branch pipe 1,0 extends uw Wardly from. the supply pipe whereby the heating agent may be carried to floors above that upon which the radiator 8 is located. S The pipe 6 is broken away in Fig. l to ndicate that it may be of indefinite length. The heating agent after extending the entire length of the system, returns by vvay of a pipe l2 through the furnace. Leading l2 is branch pipe 13 having' a section let conrmuni-.eating with a motor device l5 which consists oit' a casing 16 in which is located a flexible diaphragm 17 connected with one extremity 95 of a stem 18, the said stem being slidable in an opening 19 formed in the top of the casing, its outer extremity being pivotally connected at 20 with the arm 2l of lever 22 which is fulcrumed at Q3 on sttionary bracket 24. The arms 2l and the l 22 each carries an adjustable Weight 25. arm 27 of the lever :22 is on the opposite side of the fulcruin from the arm 2,1 and is pivot all;r connected at 28 with a link having a slot 30 through which passes a pin 3l connected by the lever 82. The lever 32 is fulc'rlnned at and has arms 34tand tending on opposite sides of the "ileruni. Upon the anni 3 5 is Inova? 't3 and 7.

ed a weight 36 provided with bali bearings 37 to facilitate its movementn upon the lever arm, the latter being provided with stops 33 and 39 to limit the movement of the weight in opposite directions. The pin 3l is attached to the arm 34 of the lever. Upon 4the extremity of the lever arm 34 is pivoted as shown at 39, a trigger 40 having ay hookshaped lower extremity 41 adapted to engage a stationary pin 42. To'thc upper arm 43 of this trigger is pivotally connected as shown at 44, to one extremity of a linlr 45, the opposite .extremity of the latter being connected as shown at 46 with one arm ot' an angle-shaped lever-47 ulcrumed as shown at 48 on an upward projection 49 of the arm 34 of the lever 32. The arm 50 of the lever 47 is connected with a lever arm 34 by a coil spring 1 which is normally under tension to hold the trigger 40 in the locked position or the ,position in engagement with the stud 42 as shown in l*`igs. l and 2, through the medium of the linlr lThe arm of' the lever 32 is connected by means ofa flexible device 52 with a damper 3 of the furnace 5. llhe flexible device 52 passes over guide pulleys 53 and 54 mounted.

on suitable stationary supports. A. flexible device 55 is connected with the device 5f, at'

oneeatremity and with an air checlr 56 at its oppositeextremity, the said check being hinged to the smoke flue 57 leading from the rear of the furnace 5.

'lhe operation of my improved devices may be explained as follows: I will assume that the heating agent from the furnace 5 passes into the radiator 8 through the pipes The first action of this agent assuming that the radiator is illed with air, is to drive out this air through the automatic airvalve 9. As soon as the air is driven out the air valve will close to prevent the escape of the heating agent which in this case is assumed to be steam. As soon as the air valve closes, the pressure within the system increases and immediately begins to act upon the diaphragm 17 causing 1t to move upwardly. lhis upward movement of the diaphragm acts through the stem 13, to lift theI arm 2l of'the lever .22 upwardly and move the arm 27 downwardly. rEhis movenient of the lever 22 acts on the lever 32, to move itsanm 34 downwardly and raise its arm 35 upwardly. This slaclrens the ilexible device 52, whereby the damper 3 is allowed to close. During this movement of the last named. damper, the air check 56 is opened through the medium of the flexible device 55 acted upon by a weight A connected with the ilegible device 52. The mechanism will remain in this position, unt-il the system cools suiiciently to produce a vacuum within the radiators, in which event the vacuum pull will act upon the diav phragm l? to move the latter downwardly to the position shown in Fig. 4. This downward movement of the diaphragm acting through the stem 1S, reverses the position of the levers and. 32, whereby the link 2S) thrust upwardly until a lug B thereon en* gages the lower extremity 4l ot the trigger and disengages the same from the stud 42. As soon as this occurs, the arm 35 of the lever 32 will move downwardly under the influence ot' its weight 36, and as soon as the lever has assumed a suitable position ot' inclination, the weight 36 will run outwardly away from the ulcrum. (see Fig. 4) giving suicient power to the lever arm, to

open the damper 3, which movement will slacken the flexible device and allow the air check to close. This operation of course will be repeated whenever the pressure within the system vary sutiiciently to accon'iplish the purpose. stood that after the devices are thrown to the position shown in Fig. 4 and the pressure rises within the system suiicicntly to throw the levers 22 and 32 to the posit-ion 'shown in Fig. l, the hook extremity 4l oi the trigger will engage the stud 42 in the locking relation owing to the tension of the spring 57 whose tendency is to actuate the lever 47 to cause the trigger' to engage the said stud.

lf `tor any reason the vacuum is broken within the system before the link 29 has moved upwardly sufficiently to disengage the trigger 40 from the stud 42, but has moved far enough to bring the upper eK- trcmity of the link above the lever 4T, l have made provision for unlocking the trigger 40 as the link and its connections move down wardly. Upon the upper extremity of the link 29 is pivotally mounted as shown at 61, an arm 60, which is held by a spring 62 in a horizontal or approximately horizontal position. The link is provided with a stop 63 which prevents the spring from throwing' the pivoted arm out of the horizont-al position. The arm of the lever 47 adjacent the link 29, is provided with a lug 64 which lies vin the path of one extremity of the arm when the link 29 moves downwardly, and the movement of the lever incident to this en` gagement, will actuate the trigger 40 sufficiently to disengage it from the stud 42, and allow the mechanism to assume the position shown in Fig. 4 whereby the damper 3 is opened and the air check closed through the agency of the flexible devices 52 and 55.

The necessity for the mechanism just explained, will only arise in case the vacuum in the system is broken by the entrance ot fluid as air, other than the heating agent. ln other words when the vacuum is broken without raising the temperature of the system, the damper 3 would still remain closed and the air checlr 56 opened which would allow the furnace fire to go out under the lt will be underb aforesaid circumstances. Hence the mechanism in question is intended to prevent this difficulty.

Having thus described my invention, what I claim is:

l. In means for regulating heating systems, the combination of a motor, constantly controlled by the system pressure, regulating devices, a suitable connection between the said devices and the motor, whereby the devices are given a predetermined movement when the system pressure acting on the motor, reaches a predetermined degree, means for locking the regulating devices in the-i said position, and connections between the motor and the 4said regulating devices, whereby when the pressure within the systcm reaches a predetermmed lower degree,

the regulating devices are actuated to trip the locking means, whereby the aforesaid movement of the. regulating devices is re versed.
